In an imaging system having at least two optically butted CCD sensors disposed in angular relation to each other and onto which light images are projected by means of a light beam splitter, the correct spacial position of the sensors is determined providing the beam splitter with mounting surfaces on which the respective sensors are mounted and the sensors with lateral surfaces, and utilizing mounting members for the opposite ends of each sensor, each mounting member having a base surface and a supporting surface extending in true rectangular fashion thereon. The base surface of each mounting member is adhesively bonded to one of the mounting surfaces of the beam splitter and its supporting surface is adhesively bonded to a lateral surface of a sensor, such bonding being effected after each sensor has been correctly aligned.
